Microsoft Teams will be receiving an update on iOS soon that will add official support for CarPlay so you can join meetings right from your car.

Although Microsoft Teams does support CallKit for accepting calls in your car when connected to CarPlay, but proper CarPlay support will allow you to join into a meeting from your car's infotainment system. While this feature is great and all, but there is one problem which we are certain you have already figured out - you can only join meetings in audio-only mode, no video support since CarPlay doesn't go that far. You can even use Siri to join meetings which is great.
